Win Window Checker
Connect your Sleeper league and see every team's dynasty window — Juggernaut, Win Now, Rising, Rebuilder, and the rest — with your team highlighted. The league's timing on one screen. No login required.
How the win window is read
Dynasty is a timing game, and most managers misread the clock — chasing win-now trades with a roster two years away, or selling a contending core after one bad week. The checker reads each roster's Edge value and age, blends them, and places every team in a phase so the league's timing is obvious at a glance.
That's the real edge: you see your own window and everyone else's. Target the rebuilder who'll sell a veteran cheap, or cash out to the contender overpaying for the last piece. What is a win window? explains the phases in depth.
The full timeline lives in the app
This checker gives you the phase for every team. The in-app Win Windows feature lays it out on a timeline and feeds your window into the AI advisor and trade verdicts, so every recommendation respects where your team is headed. Start free to unlock it.
Frequently asked questions
What is a win window?
A win window is the dynasty phase a team is in — from Juggernaut and Win Now down to Rebuilder and Basement. It blends each roster's Edge value with its age to tell you whether a team is built to compete now or building toward a future season. That should drive every trade and roster decision.
Does it classify the whole league?
Yes. Connect once and every team in your league gets a phase, with your team highlighted — so you can spot who's selling, who's all-in, and exactly where you fit before you make an offer.
Does it work for redraft leagues?
It auto-detects dynasty vs. redraft. Redraft leagues don't have a multi-year window, so those teams are labeled contender / in-the-hunt / spoiler based on projected strength and record instead.
What are Edge values?
Edge is SharperSunday's in-house dynasty value model, trained on real Sleeper trade and market data. The win-window engine reads each roster's Edge values and ages to place every team in its phase — the same engine behind the in-app Win Windows feature.
